I purchased this case from a retail store - I won't mention the name, but it rhymes with Shmarget. One of the pesky things about mobile phones is that you use them to make and answer calls from time to time. And the thing about the iPhone is that, rather than hard buttons, you have a touchscreen to control the phone's functions. When I started having problems with my phone while in this case, I did a bit of research. Wisely, the folks at Apple built in a "proximity sensor," located to the left of the earpiece. This detects when the phone is close to the face and shuts off the touchscreen so that "buttons" are not activated by the face, as well as preserving the iPhone's precious battery life. The design of this case (and many other cases, for that matter) covers the proximity sensors so that one of two things happen: Either the touchscreen remains on and active, subject to touches of the face or, if by some act of fate the touchscreen is off when you're making your call, when you remove the phone from your ear and go to hang up the call or otherwise use your touchscreen - you can't. The touchscreen remains off and inactive. Your only choice in both cases is to remove the phone from the case...which completely defeats the purpose of a case of this design. I wish that Case Logic (as well as other phone accessory manufacturers) would spend just a bit of time testing their products before putting them on the market. I suppose this is what happens when you put profits above product quality and customer satisfaction.
I'm completely disappointed by this product and hoping to someday find a similar, well-designed case that does not rob the phone of its functionality.
Seriously don't. The design is flawed. You will not be able to shut your phone off while it is in this case. Unless you really feel like cutting the ear hole longer to accommodate the light sensor it's just not going to work right.
Other than that it's a great case, but what's the point if it makes your phone malfunction?
